Error with raycast

Hello, In one of my scripts unity is telling me:

Assets/Scripts/Weapons/Laser.cs(76,37): error CS1061: Type UnityEngine.RaycastHit[]' does not contain a definition for transform' and no extension method transform' of type UnityEngine.RaycastHit[]' could be found (are you missing a using directive or an assembly reference?)

and here is my code:

 using UnityEngine;
 using System.Collections;
 
 [RequireComponent (typeof(LineRenderer))]
 
 public class Laser : MonoBehaviour {
     
     public float laserWidth = 1.0f;
     public int damage = 5;
     public float noise = 0f;
     public float maxRange = 10.0f;
     public Color color = Color.green;
     
     
     LineRenderer lineRenderer;
     int length;
     Vector3[] position;
     //Cache any transforms here
     Transform myTransform;
     Transform endEffectTransform;
     //The particle system, in this case sparks which will be created by the Laser
     public ParticleSystem endEffect;
     Vector3 offset;
 
     
     // Use this for initialization
     void Start () {
         lineRenderer = GetComponent<LineRenderer>();
         lineRenderer.SetWidth(laserWidth, laserWidth);
         myTransform = transform;
         offset = new Vector3(0,0,0);
         endEffect = GetComponentInChildren<ParticleSystem>();
         if(endEffect)
             endEffectTransform = endEffect.transform;
     }
     
     // Update is called once per frame
     void Update () {
         RenderLaser();
     }
     
     void RenderLaser(){
         
         //Shoot our laserbeam forwards!
         UpdateLength();
         
         lineRenderer.SetColors(color,color);
         //Move through the Array
         for(int i = 0; i<length; i++){
             //Set the position here to the current location and project it in the forward direction of the object it is attached to
             offset.x =myTransform.position.x+i*myTransform.forward.x+Random.Range(-noise,noise);
             offset.y =myTransform.position.y+i*myTransform.forward.y+Random.Range(-noise,noise);
             offset.z =i*myTransform.forward.z+Random.Range(-noise,noise)+myTransform.position.z;
             position[i] = offset;
             position[0] = myTransform.position;
             
             lineRenderer.SetPosition(i, position[i]);
             
         }
         
         
         
     }
     
     void UpdateLength(){
         //Raycast from the location of the cube forwards
         RaycastHit[] hit;
         hit = Physics.RaycastAll(myTransform.position, myTransform.forward, maxRange);
         int i = 0;
         while(i < hit.Length){
             //Checks if the laser hits a mech's center collider
             if(hit[i].collider.tag == "Mech Center")
             {
                 hit.transform.SendMessageUpwards("ApplyDamageCenter", damage);
             }
 
             //Checks if the laser hits a mech's right arm collider

             {

             }
 
             //Checks if the laser hits a mech's left arm collider
             if(hit[i].collider.tag == "Mech Left Arm")
             {

             }

             if(!hit[i].collider.isTrigger)
             {
                 length = (int)Mathf.Round(hit[i].distance)+2;
                 position = new Vector3[length];
                 //Move our End Effect particle system to the hit point and start playing it
                 if(endEffect){
                     endEffectTransform.position = hit[i].point;
                     if(!endEffect.isPlaying)
                         endEffect.Play();
                 }
                 lineRenderer.SetVertexCount(length);
                 return;
             }
             i++;
         }
         //If we're not hitting anything, don't play the particle effects
         if(endEffect){
             if(endEffect.isPlaying)
                 endEffect.Stop();
         }
         length = (int)maxRange;
         position = new Vector3[length];
         lineRenderer.SetVertexCount(length);
         
         
     }
 }
 

Does anyone see what is wrong?
